Clamping and feeding device of machine tool for machining long-strip-shaped parts

The invention discloses a clamping and feeding device of a long-strip-type part machining machine tool, relates to the technical field of machine tools, and aims to solve the technical problem that in the prior art, the head section or the tail section of a long-strip-type part is suspended and is difficult to keep stable during machining, so that the machining precision is reduced. A Y-axis moving mechanism, a movable clamping mechanism and a fixed clamping mechanism are arranged on the base, the Y-axis moving mechanism is used for driving the movable clamping mechanism to move in the Y-axis direction, the movable clamping mechanism and the fixed clamping mechanism are used for clamping long-strip-shaped parts, a groove body is further formed in the base, a lifting mechanism is arranged in the groove body, and the lifting mechanism is used for lifting the long-strip-shaped parts. An auxiliary side clamping mechanism is arranged on the upper portion of the lifting mechanism, arranged between the movable clamp
